Narrative Opinion Summary
The case involves an appeal by a defendant convicted of first-degree reckless homicide and second-degree recklessly endangering safety, challenging the evidentiary rulings of the circuit court. The defendant argued that the court improperly excluded testimony from her firearms expert, which she claimed was crucial for supporting her defense that the shooting was accidental. The court found that the expert’s testimony did not meet the admissibility criteria under WIS. STAT. 907.02, as it lacked a sufficient factual basis and reliable methodology. The defense also challenged the inclusion of the State's forensic expert's rebuttal testimony, contending it was beyond the expert's qualifications and irrelevant. However, the court ruled that the expert was sufficiently qualified and that the defendant forfeited her right to appeal one of the rebuttal questions by not objecting during the trial. The appellate court affirmed the lower court's decisions, emphasizing the circuit court's role in ensuring expert testimony is both reliable and pertinent, and upholding the conviction as the defendant failed to demonstrate that the evidentiary rulings were erroneous.
